You went to Device Manager, Disk Drives right?
If you installed chipset inf updates, IDE drivers from your mainboard CD-ROM or other, than you may not have a DMA checkbox. Does your drive show up as Generic IDE, or as Maxtor, Quantum whatever..
If the latter, than your DMA is most likely already set, and lack of the DMA checkbox is normal.

Usually DMA checkboxes will disappear if the driver sets the DMA on.
If the device is not-DMA capable or 98 doesn't have a driver that tells it it is DMA capable, the DMA checkbox is present. If 98 sees the device as DMA capable, it removes or grays out the box and permanently enables DMA.
Confusing, ain't it?

You are absolutely right. When I updated my mobo driver, it took over the DMA settings. Now it lets me set DMA to ATA33, 66 or 100. Anyone know what this means & which is best?

Umm DMA 100 is the best.
it's basically the peak transfer rate between a HDD and the computer motherboard. The higher the better.
However 100 does not mean it will be at 100 MB/s all the time. Only peak (like the last part of the transfer when its dumping cache contents).
